I was reading that the average American home energy costs is about $300 per month or $3,477.

Referring to electricity and gas (not phone or water, etc.) This is about half what I pay, and I wondered if this sounded right to you? Mine varies from about $65 (spring and fall) to $120 (winter and summer). I realize I live in a small apartment/townhome (800 SF; all electric) so an entire house would run more.
